By comparing Figure 5 (c) and elastic time history analysis and response spectrum method calculated interlayer displacement angle did not exceed the allowable value of drift angle of 1 / 800, can meet the requirements of specification and transform of seismic wave interlayer displacement angle value, the overall to response spectrum curve near.

But given that this model was buckled in drift angle (rotation) of 0.03 radians, according to AISC Regulations it has no usability in especial moment frames, because one of the terms of especial buckling connections is that studied will not be declined before reaching the rotation angle of 0.04 radians.

Meanwhile, the drift angle is read by looking at the number of degrees on the slide under the dot as it differs from the course.

The fundamental parameter for investigation of seismic performance is the inter-storey drift angle. Basedon the data collected by photographic documentation, data logger, and direct observation, it was concluded that initiation and propagation of cracks were observed at the same storey shear force in all specimens.

And Figure 10(b) shows the cracks on the shear wall when the drift angle is 1/120 (that is a safety limit under severe earthquake according to Chinese seismic code).

where: L--ship length (maximum overall); B--ship width; [beta]--the drift angle of a ship while proceeding to the channel; [DELTA]K--the sway angle of the vessel along the course while heading through the channel; [b.sub.nav]--navigational margin depending on the aids of a navigation system, channel slope accuracy, etc.; P'--probabilistic maintenance factor in case the probability is 95% as accepted in navigation, thus P for channels is about 2; [[sigma].sub.y]--ship positioning accuracy in a way of the channel axis, e.g.

Evaluating the width of navigational channels

This value can be computed assuming the yielding value of the first storey drift angle conventionally equal to 0.004 rad, which approximately corresponds to a base shear equal to 40% of its maximum value, hence [mu] = 0.056/0.004 = 14.
